WebTypes of Substitution Reaction. 1. Nucleophilic Substitution. When electron-rich species (nucleophile) provides an electron pair for bonding with the compound being transformed, it is called nucleophilic substitution. Some examples of nucleophiles are Cl –, Br –, I –, OH –, RO –, CN –, H 2 O, and NH 3. WebDigital subtraction angiography (DSA) is a new radiographic technology used in diagnosing vas- cular disease.
